SUPERHEATER.

Application filed. February 6, 1922.

To (all whom Be 1t known may concern: that we, WILLIAM F. Hrnns and VVILLLiM H. Crninn, citizens of the United States residing at lllountaiu flGW 7 s1 n and l aicines, respectively, in the counties or Santa Clara and San Benit'.) respectively, and titate of lalifornia, have invented. new and useful liuprovement-s in Superheaters-s, of which the following is a specification;

This invention relates to improvements in super-heaters for internal combustion en- PHIGS. o l o Q o u The principal ob ect of this invention 18 to provide means for introducinga blast oftion and highly eflicient in use.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevation of an intake manifold, having our invention applied thereto, and

Fig. 2 is a cross-section taken on the line 2-2 of Figure 1.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 5 designates an exhaust manifold and the numeral 6 refers to an intake manifold of conventional construction; As disclosed to advantage in Figure 1, we have provided a hood 7 which is adapted to extend over the exhaust manifold 5, and is closed at its ends as shown at 8. This latter construction is set forth to advantage in Figure 2. The hood is preferably supported by an upwardly extending portion 9 formed integral with the hood, which portion is adapted to be clamped as by the usual spreader 11. A casting 12 is bolted or otherwise secured to the intake manifold by bolts 13 and 14. or other suitable fastening ele- Serial No. 534,474.

ments, the bolts passing through flanges 16 and 17 which have interposed therebetween a gasket 17.

The numeral 18 designates a hollow chamher which is provided in the casting 12,

which chamber hasan intake port 19 and an outlet port 21, which latter port is adapted to be closed by a valve 22 carried upon a valve stem 23. It will be noted that the valve stem passes upwardly through a spring cage 24 which cage is adapted to retain a compression spring 25 one end of which bears against the bottom of the cage 24: and bears upwardly against a washer 26. A suitable boss 27 is provided on the under face of the washer while a boss 27 is integrally formed in the lower surface of the spring cage 24. These bosses serve to retain the spring in a normally vertical position, while a winged nut 28, screwed on the 7 stem 23 functionsto complete a compact arrangement.

The inlet pipe 19 above referred to, is adapted to connect with the carburetor port 29 and extends to the usual carburetor 31. A cover 32 is placed over the spring cage and the same is fastened thereon in any conventional manner.

At 33 We have shown a pipe entering the hood 7 and provided within its length with 8 or coupled thereto a valve 34, which valve is controlled by a handle 36. Adapted to be positioned on this valve is a priming cup 37 for the purpose of starting during cold weather when it is desired to introduce gasoline directly into the manifold. The numeral 38 designates a port which serves as a means for communication between the casting 12 and the valve 34.

The operation of our device is as follows:

After the engine has been running and the exhaust pipe has become hot, heated air is taken from the hood 7 through the pipe 33, and valve 34; into the chamber 18. At the same time gaseous vapor is being taken from the carburetor through the pipe 29, port 19. into the chamber 18. The suction of the engine causes the valve 22 to move downwardly against the spring 26 with the result that gaseous vapor is taken into the intake manifold 6 and at the same time a hot blast of air from the hood 7 is sucked into the chamber and mixed with the gaseous vapor. The resultant mixtures is very explosive and consequently we find it possible to secure many more miles per gallon by the employment of our device.

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope .of the su] joined claims.

Having thus described our invention, we claim:

1. In a device of the character described, the combination of a casting adapted to receive carbureted air, means for delivering heated air to said casting and means for discharging said carbureted air and said heated air to an intake manifold of an internal combustion engine, said discharge means being opened by the vacuum in said intake manifold.

2. In a device of the character described, the combination with an exhaustmanifold, of a hood covering a portion of said manifold, a casting having a chamber therein, and provided with an inlet and outlet port, a spring pressed valve adapted to close said outlet port, an inlet manifold connected to said casting and adapted to receive a dis charge from said outlet port, a carburetor connected to said inlet port and means for conducting heated air from said hood to said chamber.

3. In a super-heater, the combination wit-h an intake manifold, of an exhaust manifold, a casting secured to said intake manifold a chamber formed in said casting, a port opening from said Casting into said intake manifold, an inlet port formed in said casting, a carburetor secured to said inlet port, a valve seated in said outlet port, tension means for holding said valve in contact with said casting, said tension means causing the vacuum in said intake manifold to overcome the same for the purpose of opening said valve, and means for delivering said heated air to said chamber.

4. In a device of the character described, the combination with an exhaust manifold, of an intake manifold, a hood adapted to receive heated air from said manifold, a.

pipe extending from said hood, a casting having a chamber formed therein, said chamber being adapted to receive heated air from said pipe, a valve located in said pipe, an inlet and an outlet port formed in said casting, said outlet port being closed by a resiliently held valve, means for delivering carbureted air to said inlet port and means for securing said casting to said intake manifold so that said outlet port will discharge therein.

In testimony whereof we afiix Our signatures.
